To aU whom it may concern Be it known .that l. ALBERT 'Envir-ARD Cinco, a subject of the King of Great Britforked head, rotatable about a vertical axis;v

and with turnover frames mounted on the lvertical sides of the forked head' and rotatable about a common horizontal axis; the connections and gearing being such. that when the head is turned around by half a revolution to bring the one of the turnover frames from the' front to back o f the machine. and thed other turnoverfraine from the backi to thei, front, both turnover frames are at the same time rotated through a half revolution. Each turnover 'frame-carries. a

air of swinging arms which ca rrjv7 at their ends the halves of the parison mold 1 1 .1 Several of such machines are usually arranged around or partially around the furnace containing the molten metal or glass, which. is poured by serversA standing at the back olf the machine intothe. parison mold. Parison is the technical term for the hot glass in the parison mold and before being blown inthe finishing mold. The

blower or attendant stands in front of the machine.

Now this invention consists in a new arrangement or combination of such machines in pairs, so that the rear sides of the two machines are so close together that o ne server can attend to two machines,4 while 'each machine has its own blower at the Afront attending to the blowing operations.

In order to be able to place the machines of each pair as close together as possible it is necessarv that the forked heads of the two machines shouldnot he rotated simultaneously, otherwisethe turn over frames or the swinging arms 1would come in Contact. This invention .makes provision for preventing such simultaneous rotation being started by the two attendants.

The invention is illustrated by the accompanying drawings. Figure l is a plan, andlig: 2 1s an elevation, the left hand side being in vertical lonv to this gitudi'nal central section tor and gear box being omitted. F ig. f3 repeats the sectional part of Fig. l on a largei scale, the spindle t being shown in its i` position and Fig. t is enlarged view of the 'recessed collar or cam.

of' and 7a2 are the pillars or pedestals of the two machines respectively, which carijv the tu'i'n over heads and blowing mechanism, not shown. The pedestals as sbown'are carh ried by bed plates ai and a2, connected at the rear by a cross'plate d, and at the front by a bent or curved cross platee or 0'). Instead of being separati-l the bed plates and cross pieces all be cast in one piece. The center vertical planes of the two machines, see and g/'g/ Fig! 1,'v are according invention inclined Ytoward one another, the inclosed angle being conveniently degrees or thereabout.

f is the first driving shaft, driven by an' of Vig l l; themoelectric-y or other motor e, the anis ofthe shaft f bisecting the angle inclos'ed by the lines ai and y y. By means of a worin on the shaft 7' and a worm wheel on the shaft z',

inclosed by the gear box h, motion 4is trans' -feried through the spur wheels j and jg re-v spectively to the wheels 7c and mounted loose on the proximate ends of two similar' alined horizontal shafts. one of o iwhich, marked 'l,1 is shown on-Fig. 2, the other being hidden by theparts which surround it;

the shafts being rotated at the proper times from the vwheels 7c and l# by means of friction driving cones, n. The ends of the said two shafts drive by means of 2 to l bevel gears 7 the vertical drivingshafts Bof the. blowing machines.

S is a stop rod, normally held in the raised position by a spring, not shown, in which position it locks the turnover 'head against rotation, and indirectly against the driving vices.. The clutch 'n' is fitted on the 'shaft Z, (or the .corresponding shaft) with a sliding key or keyway, so that .1t can be y collar' r fixed on the shaft'Z.`

The spiral spring is surrounded by the muil or sleeve 0, which is secured to the boss pressed against the internally coned rim of thewheel Ic (or k2.) by the spiral spring g, which bears at its other end against lthe respect to the collar of the sleeve o, that when the cone clutch '1v/'is pressing against c, seethe left side of Fig-2, the upper end of the spindle t springs upward into the recess \s, when the'rotary movement brings the recess opposite the upper end of the spindle t. l 2O causes the upper end of the spindle t 'to 4The continuation of the rotary .movement force back the sleeve o, see the right side of Fig. 2, and with it the clutch .cone n, thus stopping the rota-tionjof the shaft Z', therefore of .the driving shaft 6 also.

The spindle t is drawn down by the de? 1 pression of the foot leverw, through they connections, shaft 1,' leven 2, link 8, b'ell crank lever 4,a'nd stud; pin t engaging in a slot in one of the arms of the bell crank lever 4. A hinged two armed. lever lO is tact, thus permitting a larger number of 5d machines being arranged around one furnace Vet carried so that its ends are always in'contact with the bottom of the two spindles, and thus while not preventing the upward movement of either of the spindles, prevents the simultaneous downward movement .of the two spindles, and hence, vthe friction clutches connecting the said two alined shafts with the motor shaft f from coming into engagement simultaneously; so that the shafts 6 and. consequently the turnover heads of the two machines cannot be rotated simultaneously i. c. independently.

This allows the two' lmachines to'be placed' closer together thancould be done if vthere s were any risk .of the turnover heads or the mechanism carried by them' coming in con- '.and dispensingiwith half the servers.

'The connected operation of the parts described is as follows: Ther` attendant or blower at one of the machinesl depresses the foot lever w of his machine, drawing down the corresponding vertical spindle t and allowing thev clutch lmechanism toconnect his machine with the driving shaft f of the motor, and-through the rever 10-to raise the vertical spindle t of the other machine so as to disconnect the driving shaft of such machine fro'm the motor shaft f. The last portion of the downward movement of the lever lw depresses the lever 9', drawing down the stop rod 8, soas to unlock the turnover head of .this machine. Whe ennesima- The outer end 'of the sleeve 0 I -sponding shaft vof'the-two'saidl shafts I i completes one revolution, the'turnover head making half a revolution, theupper'end of,4

the corresponding spindle t; springs iup-into the recess s, an"dt hus arrang s the'parts for. v7.0 action which. brings the mac 'incida' stand# still, the foot lever w bein brought/tdfits original position. .As the spindles 'jrherely -Lrest on the ends'of the level' 10, the other machine is not started until the' otherblower 75 oratte'ndant depresses his'footllever w. `The starting ofeach machine is thus absolutely under-the controlof'itsattendant. v
